Abstract
A typical embodiment of the invention provides a sturdy, lightweight, inexpensive and comfortable warmer for fresh breathing air. An heat exchanger that is sufficiently flexible to conform with the shape of a wearer's scalp is secured to the wearer's head by means of a pullover cap. In this way the heat exchanger takes advantage of the great heat dissipating capabilities of the human head in order to warm fresh breathing air on its way from the atmosphere to the wearer's nose mask.
